Fully-closed Modules and Safety Modules
Note: You cannot use a Fully-closed Module and a Safety Module together.
*1. If you combine a Σ-7-Series SERVOPACK with a Σ-V-Series Option Module, the following Σ-V-Series SERVO-
PACKs specifications must be used: a surrounding air temperature of 0°C to 55°C and an altitude of 1,000 m
max. Also, the applicable surrounding range cannot be increased by derating.
*2. The coefficient of speed fluctuation for load fluctuation is defined as follows:
No-load motor speed - Total-load motor speed
Coefficient of speed fluctuation =
× 100%
Rated motor speed
*3. Always perform risk assessment for the system and confirm that the safety requirements are met.
